Polycarbonate Track Etched Membrane Filters, 0.2um, 13mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215610

Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, this Polycarbonate Track Etched (PCTE) membrane disc delivers a 0.2um pore size across a 13mm diameter for accurate surface-capture filtration. The membrane is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, so it can be used directly in water and aqueous solutions without pre-wetting. Its smooth, flat, glass-like surface captures all particles larger than the pore size on the membrane face, making it well suited for microscopic and optical analysis.

Key Polycarbonate Track Etched Membrane Characteristics

• Hydrophilic surface: PVP treatment allows immediate wetting in water and aqueous solutions without pretreatment.
• Precisely defined pores: A two-step track-etch process creates uniform, cylindrical pores with controlled pore size and density.
• Surface capture: The smooth, flat structure retains particles larger than the pore size on the membrane surface for clean recovery and analysis.
• Low protein binding: The thin polycarbonate film minimizes nonspecific binding and resists chemical staining for easier microscopic visualization.
• Translucent, glass-like surface: The thin film offers superior particle visibility suited to optical and microscopy applications.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film, white membrane.
• Format: 13mm diameter membrane disc, plain (not gridded).
• Sterility: Nonsterile.
• Pack: 100 discs per pack.

This membrane provides consistent, well-calibrated pore structure for reliable particle retention and reproducible results. Its uniform surface and low binding characteristics help preserve sample integrity during clarification, particulate analysis, and microscopy.

• Particulate Analysis The smooth, surface-capture structure collects particles larger than 0.2um on the membrane face for clean microscopic counting and characterization.
• Fluid Clarification The 0.2um pore size removes fine particulate from aqueous samples and reagents.
• Cell Biology and Bioassays The low protein binding and biocompatible polycarbonate film supports cellular-based filtration assays.
• Microscopy and Optical Analysis The thin, translucent, glass-like surface enables superior particle visibility for microscopic examination.
• Water Microbiology The hydrophilic, precisely pored membrane supports microbiological water testing and sample preparation.
• Blood and Plasma Filtration The defined pore structure aids in separation and removal of cellular components from aqueous biological samples.
